一、集羣軟硬件環境準備：
操作系統： centos 7 x86_64.1804
Ambari版本：2.7.0
HDP版本：3.0.0
HAWQ版本：2.3.0
5臺PC作爲工作站：
| ep-bd01 | ep-bd02 | ep-bd03 | ep-bd04 | ep-bd05 |
其中ep-bd01作爲主節點，用於安裝ambari-server。
二、配置操作系統，安裝必備軟件
1，CentOS7操作系統環境配置，安裝必備軟件。
2，安裝配置NTP服務，保證集羣時間保持同步，以防止由於時間不同而造成掉線故障。
詳細看隨筆：基於【CentOS-7+ Ambari 2.7.0 + HDP 3.0】搭建HAWQ數據倉庫之——安裝配置NTP服務，保證集羣時間保持同步
見《安裝配置NTP服務》
3，安裝MariaDB Server用於Ambari server以及Hue和Hive
詳細過程，參見：基於【CentOS-7+ Ambari 2.7.0 + HDP 3.0】搭建HAWQ數據倉庫之一 —— MariaDB 安裝配置
4，安裝yum priorities plugin
yum install yum-plugin-priorities -y
三、搭建本地倉庫：
1，下載軟件包：
cd /root mkdir downloads cd downloads wget http://public-repo-1.hortonworks.com/HDP-GPL/centos7/3.x/updates/3.0.0.0/HDP-GPL-3.0.0.0-centos7-gpl.tar.gz wget http://public-repo-1.hortonworks.com/HDP/centos7/3.x/updates/3.0.0.0/hdp.repo wget http://public-repo-1.hortonworks.com/HDP/centos7/3.x/updates/3.0.0.0/HDP-3.0.0.0-1634.xml wget http://public-repo-1.hortonworks.com/ambari/centos7/2.x/updates/2.7.0.0/ambari.repo wget http://public-repo-1.hortonworks.com/HDP-UTILS-1.1.0.22/repos/centos7/HDP-UTILS-1.1.0.22-centos7.tar.gz wget http://public-repo-1.hortonworks.com/HDP/centos7/3.x/updates/3.0.0.0/HDP-3.0.0.0-centos7-rpm.tar.gz wget http://public-repo-1.hortonworks.com/ambari/centos7/2.x/updates/2.7.0.0/ambari-2.7.0.0-centos7.tar.gz
2、搭建本地倉庫：
安裝並開啓Apache HTTP服務
yum install httpd -y systemctl enable httpd systemctl start httpd
確保/var/www/html目錄存在，沒有的話創建。
mkdir -p /var/www/html
創建HDP，HDF子目錄
cd /var/www/html mkdir hdp hdf
解開下載的軟件包：
cd /var/www/html tar -zxvf /root/downloads/ambari-2.7.0.0-centos7.tar.gz -C . tar -zxvf /root/downloads/HDP-3.0.0.0-centos7-rpm.tar.gz -C ./hdp tar -zxvf /root/downloads/HDP-GPL-3.0.0.0-centos7-gpl.tar.gz -C ./hdp tar -zxvf /root/downloads/HDP-UTILS-1.1.0.22-centos7.tar.gz -C ./hdp
修改下載的ambari.repo，
vim ambari.repo
安裝如下內容修改，[注意版本號，需要根據具體下載的版本不同修改，解壓後自己查看一下]：
#VERSION_NUMBER=2.7.0.0-897
[ambari-2.7.0.0]
#json.url = http://public-repo-1.hortonworks.com/HDP/hdp_urlinfo.json
name=ambari Version - ambari-2.7.0.0
baseurl=http://ep-bd01/ambari/centos7/2.7.0.0-897
gpgcheck=1
gpgkey=http://ep-bd01/ambari/centos7/2.7.0.0-897/RPM-GPG-KEY/RPM-GPG-KEY-Jenkins
enabled=1
priority=1
複製到/etc/yum.repos.d
cp ambari.repo /etc/yum.repos.d/ambari.repo
修改下載的hdp.repo，
vim hdp.repo
安裝如下內容修改，[注意版本號，需要根據具體下載的版本不同修改，解壓後自己查看一下]：
#VERSION_NUMBER=3.0.0.0-1634
[HDP-3.0]
name=HDP Version - HDP-3.0.0.0
baseurl=http://ep-bd01/hdp/HDP/centos7/3.0.0.0-1634

gpgkey=http://ep-bd01/hdp/HDP-UTILS/centos7/1.1.0.22/RPM-GPG-KEY/RPM-GPG-KEY-Jenkins
enabled=1
priority=1
保存退出，複製到/etc/yum.repos.d/
cp hdp.repo /etc/yum.repos.d/hdp.repo
四、主節點安裝ambari server
1，使用剛纔配置好的本地倉庫，直接yum命令安裝。
yum install ambari-server -y
2，查看ambari server 狀態
systemctl status ambari-server ● ambari-server.service - LSB: ambari-server daemon Loaded: loaded (/etc/rc.d/init.d/ambari-server; bad; vendor preset: disabled) Active: inactive (dead) Docs: man:systemd-sysv-generator(8)
看到ambari server已成功安裝了。
3，配置mariadb，建立用戶和數據庫供ambari使用
建立數據庫用戶ambari
mysql -uroot -p
MariaDB [(none)]> use mysql;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
MariaDB [mysql]> grant all privileges on *.* to 'ambari'@'%' identified by 'ambari';
Query OK, 0 rows affected (0.06 sec)
MariaDB [mysql]> flush privileges;
Query OK, 0 rows affected (0.00 sec)
MariaDB [mysql]>
建立數據庫ambari，並運行ambari數據庫建表sql命令文件。
MariaDB [mysql]> create database ambari; Query OK, 1 row affected (0.01 sec) MariaDB [mysql]> use ambari; Database changed MariaDB [ambari]> source /var/lib/ambari-server/resources/Ambari-DDL-MySQL-CREATE.sql; Query OK, 0 rows affected (0.01 sec) Query OK, 0 rows affected (0.00 sec) Query OK, 0 rows affected (0.00 sec) Query OK, 0 rows affected (0.06 sec) Query OK, 0 rows affected (0.00 sec) Statement prepared ... ...
4，配置ambari server
執行命令
ambari-server setup
回答選擇項，其中JDK選擇“”Custom“”，給出系統安裝目錄，數據庫一定要選擇高級配置，指定mariadb數據庫和用戶，本人系統中詳細過程如下：

5，命令行方式設置mysql數據庫連接庫，用於oozie和ranger連接mariadb時使用（上面設置後不起作用，必須如下操作）：
ambari-server setup --jdbc-db=mysql --jdbc-driver=/usr/share/java/mysql-connector-java.jar
6，配置ambari-server自啓動，啓動ambari-server

ok，Ambari-server安裝完成。瀏覽器訪問ambari-server服務：
http://ep-bd01:8080
默認用戶名/密碼爲：admin/admin，登陸後界面如下：
五、所有主機節點，安裝ambari-agent，並配置自啓動
yum install ambari-agent -y && systemctl enable ambari-agent
systemctl start ambari-agent && systemctl status ambari-agent
